layer and polygon

[Eveline Franken]

Hi,

I have multiple overlapping layers. I would like to change visability of a
layer by clicking on a polygon. Any idea how the code should look like?

Thanks in advance,
Eveline

Assuming you have an area map just to toggle layer(s)' visibility, then

<img alt="to be defined" height="234" src="path/filename.ext" title="to
be defined" usemap="#MapArea" width="345">

<map name="MapArea">

<area alt="to be defined" coords="x1, y1, x2, y2, ..., xN, yN" nohref
onclick="if(document.getElementById('targetLayerId').style.visibility ==
'visible') {document.getElementById('targetLayerId').style.visibility =
'hidden';} else
{document.getElementById('targetLayerId').style.visibility =
'visible';}; return false;" shape="poly">

Next time, please provide more details like url to view your webpage,
browsers to support, rendering mode, etc..
